This passage, which appears in tests like the IELTS Trainer 2 , challenges readers to identify specific details and assess facts. Below are the correct answers and detailed explanations, based on the standard passage.
Excessive runoff of fertilizers introduces nutrients like phosphorus, leading to a destructive process called [eutrophication] .
The text explicitly mentions multiple compounding factors, including agricultural river diversion and industrial pollution, meaning global warming is not the sole (only) reason. earth lakes are under threat reading answers
This article explores the primary threats—eutrophication, climate change, plastic pollution, and water extraction—and provides a simulated section to help students, educators, and researchers understand the key facts and solutions.
The story of the world's lakes today is one of rapid transformation and fragility. Once-vast bodies of water are disappearing or changing fundamentally due to a combination of climate change and human activity. The Disappearing Giants This passage, which appears in tests like the

The core of this discussion revolves around an academic reading passage that presents a sobering picture of the state of the world's lakes. The text uses several case studies to illustrate the diverse threats, and it’s crucial to understand these examples before tackling the questions. Once-vast bodies of water are disappearing or changing
Beyond climate, direct human intervention is devastating lake ecosystems. Agricultural irrigation accounts for 70–80% of global freshwater withdrawals, often diverting rivers that feed lakes. The Aral Sea—once the fourth-largest lake in the world—has shrunk to 10% of its original volume due to cotton irrigation in Uzbekistan and Kazakhstan. Similarly, the Dead Sea is receding at over one meter per year due to potash mining and upstream water diversion. Unsustainable groundwater pumping further lowers water tables, causing lakes to drain into aquifers below.
Some of the world's most iconic lakes are facing significant threats, including:

Elara stepped forward. "Not like this, Mr. Henderson," she said, her voice calm but firm. "The study I submitted last week—the answers you’re looking for—aren't just about the rain. It's the runoff. The fertilizers from the farms north of us, combined with the rising temperatures, are turning the lake into a petri dish. We aren't just losing water volume; we're losing oxygen. The fish are already dying."
